The chain of this necklace is actually quite old. Heavy duty oxidized copper that has been sealed to retain it's color.  The stones that interupt the chain are agates, other than the olive green pieces, which are jade.  I wrapped the centerpiece in hand oxidized brass filigree. It is fused glass-glass combined and melted down in a kiln. Butterflies hold a special place in my heart, for they are a symbol of change and transfomation. We all have beauty within us.  This necklace is 20 inches long.
